Looking back at my friend Liam from the top of the tricky slab finish of Thin Air. This is the direct/right line. The other option is to stay to the left and follow up a dirty/easy corner. I think this finish was very cool and probably more fun than the dirty corner would have been, but please note that there is no protection for the last slab section. It's pretty low angle and only about 8 feet tall, but does require some good slab technique.
